blueprint

[faint pasture]

@true quartz Then put that in the meteor BP

Has nothing to do with the spawner.

[true quartz]

But the problem is I dont know what to put in there that will make it work

[faint pasture]

Event Hit or whatever the equivalent is for however you're moving your meteors

Then on event hit, play sound at hit location. Easy peasy

[vague shell]

How can I get the location of a bone relative to its bind pose?

[opal ivy]

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Spline/GetVectorPropertyatSplinePoint/ where is the Setter for this?

[faint pasture]

@opal ivy Editing the spline

[opal ivy]

I want to add a property programmatically.

[faint pasture]

Oh hmm. What's your options for making spline points?

[opal ivy]

I'm generating them all at runtime and want to shove an extra piece of data on

[faint pasture]

Is that the only node that has to do with Vector Property or Metadata?

[opal ivy]

It's possible there are more, but I didn't see any other than the various tangents and vectors associated with the points themselves

[faint pasture]

Do you have access to the custom vectors when placing points manually? Not at my computer ATM

[prisma stag]

Anyone ever have this problem?

[faint pasture]

@olive sedge Just google vector, dot product, cross product, and Euler angles. Rotations are quaternions behind the scenes(I think) but presented to you as ruler angles.

@prisma stag ya it's a focus issue. Also what input mode are you setting it to?

[prisma stag]

So after releasing tab to close the menu to make your selection, I have it set back to Game Only.

However, I noticed that when I make my selection, the menu and cursor automatically disappear, so I didn't know if that changes any other settings.

[faint pasture]

Set it to UI only when menu is open

[prisma stag]

That works, however, whenever I right click it disables the mouse being able to move the camera, which Im okay with, but you have to double click for it to place.

[true marsh]

Can you change the outer of a base object in blueprints?

[hoary gazelle]

I was doing some research and I still cant find out how to make a percentage based gacha system.
Is there anyone that can point me in the right direction with this? Im having a difficult time trying to work around it.

[true marsh]

@hoary gazelle For what, card drops / pack openings?

[hoary gazelle]

Mostly just skins/weapons

Similar to mobile games and how their gachas are

[trim matrix]

So nobody knows why my project got so excessively bright when I upgraded it to 4.26? Is there anything in the newer version of the engine that messes with the lighting effects?

[faint pasture]

@trim matrix probably depends on what version you upgraded from. I know there was a transition to a new auto exposure setting recently.

[true marsh]

The simplest is just a random roll of some sort, than pull from a set of skins/weapons from that category. You could look in to how random works + seeding randoms for more "true" random. Typo in this image, Legendary would be 1%.

[hoary gazelle]

So if the rare roll has an integer greater than 0 wouldn't that automatically call the common first, since 20 is also greater than 0?

[faint pasture]

@hoary gazelle its checking if roll is greater than 20

That'll only return true if you roll 21 or higher

[hoary gazelle]

Yeah thats what im getting at.
If the rare roll is 0, it would have to grab a number 1 or higher to get it right?
What if it was 21 would it get the common or the rare, or even the uncommon?

[dark crow]

21 to 100 -> Common
6 to 20 -> Uncommon
2 to 5 -> Rare 4%
1 -> Rare 1%
0 -> Nothing

[hoary gazelle]

ah okay i get it now.
Thank i appriciate it!

[true quartz]

I have been doing that and to no avail it doesnt work

The meteors are just falling out of the sky also @faint pasture

[faint pasture]

Show your hit event

[true quartz]

ok

and yes i know the sound and emitter are off right now I just made this again

[warped cairn]

Okay. desperately need help... I am attaching my actor to an empty sphere collider, the only issue is I can't seem to detach it.... Here is what I have done.

The reason I am using this, is because it needs to attach to the actor when they collide with a box, that box will then be deleted.

[dawn gazelle]

Is your intention to have the sound only trigger when the meteors collide with each other?

[true quartz]

only when it hits the ground

[dawn gazelle]

Then your cast is blocking what follows. "Other Comp" would be a component on the thing that was hit by a fallingmeteor.

[true quartz]

i updated it sorry I forgot to post

[dawn gazelle]

Same thing.... "Other" in this case would be an actor and your cast will block anything further unless it is a falling meteor.

[true quartz]

so waht would I want to connect to?

[dawn gazelle]

get rid of the cast.

[true quartz]

no good 😦

I just dont get why it wont work no matter the config

[dawn gazelle]

Put a print string in right after your event hit node. See if it actually gets called.

[true quartz]

ok

it was never called

ok so now i am getting somehwere lol

on com hit and on event hit dont work

with this one it plays the sound and emitter on spawn

@dawn gazelle

[dawn gazelle]

Might want to make your box collision the root of the object, and make sure your collision settings are right.

[true quartz]

do I hit at location impact or what?

[lost solstice]

anyone know how the vaulting system from the ue5 demo was done at all or what I could look up to find something simlar

[true quartz]

sorry to be a bother I just really want to get this done since I have spent hours on it

I just put in a delaay and cheated the system I cannot figure it out

but hey ti works

[opal pendant]

anyone have any idea why I'm getting this error?
the error is within the "Manipulate Int Internal" and it happened after I compiled a function with an integer increment node inside of it

I'm on UE 4.26 source built if that makes a difference

[sand shore]

wouldn't you assign to the macro variable?

@opal pendant that probably won't fix it because macros are a special kind of pain

You'd be better served with a CustomThunk c++ function

[opal pendant]

I didn't even make the macro

it's just what came up after I tried to use the Increment Int function

[sand shore]

Oh.

Welp.

[true marsh]

In my example i actually did a random from 1 - 100 so 0 were never show up. 1 is the last number available so if it is at that point the only option left is 1. You could also do a random float 0 - 1 float for .05 chances or use 1 - 1000 as an integer.

[true marsh]

It looks like the detach node is not connected to the right pin? Should it be connected via the cast to player or "self"?

[vague shell]

would appreciate some help

[true marsh]

Do you need specifically the bone or are you using sockets?

The initial thoughts is to save the location on startup (event begin play or similar) than save the new location and use math to compare the two locations in some way.

Which you might have to set the bind pose for a second or two, save the location, then set the animation instance class

[trim matrix]

Was there one from 4.23 to 4.26?

[true marsh]

In your post process check on min/max brightness

Well technically you might need to check the same setting on your character camera as well, any camera that the player is using will have that setting but post process does too

[trim matrix]

Thank you for the suggestion, but it does not appear to have fixed it.

I think there are some larger forces at play here, I just now noticed that the foam, reflections and shadows on the ocean are gone too.

I won't clog this channel with the same question again. I will try my best to find the solution to this upgrade problem. Thanks for the help!

[warped cairn]

I sorted it, since both elements are always in the game, and I have a flipflop to toggle in the level blueprint, I just done it there. 😛

But I seem to be running into another problem.... -_- I just made this rather lovely options menu, and spent about an hour typing commands in, but they don't work 😢

[chilly jetty]

hi I have a question

if i destroy an actor and down the line i have a delay in the bp

with the delay still go through?

[dawn gazelle]

No.

[chilly jetty]

mmm i thought so

[warped cairn]

Didn't work

[dawn gazelle]

Won't work if you're playing in viewport.

Run as a standalone game, works fine.

[warped cairn]

Ah, I had no clue I needed to make the gamesettings.ini file

[crimson saddle]

Since the umg chat seems to be completely dead I'm gonna try asking here too

[vocal urchin]

I'm not sure why this would be any different, but this is most definitely not working, and is instead spawning the particle system at the level's origin instead of at my component's transform.

[crimson saddle]

How do I add values to a ComboBox in a ListView during construction?

On the surface it feels like this is an impossible task, as any attempt at referencing the ComboBox returns null, and I would need to call another function (somehow) in order to go through my ListView (a second time) to update every ComboBox after construction

I feel like there must be an elegant way to keep my entry widget information up to date. Unfortunately someone was sleeping when they implemented the ComboBox and you can't bind anything to it for... some reason

[dawn gazelle]

Relative Transform is saying the position of the object relative to it's parent. So if you have the Hull Mesh at 0, 0, 0 on your actor, then spawning a particle system at the relative transform of that Hull Mesh, it'll spawn it at the world position of 0, 0, 0

Get World Transform is probably what you want.

[vocal urchin]

Still doing the same thing, strangely. I thought the same thing and tried it right after.

[chilly jetty]

does a set timer by event work even after the actor is destroyed?

[true marsh]

Anyone know if this "DO NOT CALL" warning is still valid? I used profiler to compare the MS difference between Spawn Actor (0.110 MS), Construct Object (0.038 MS) and Add Scene Component (0.009 MS) and its actually the fastest. I'm curious if there is some other reason to avoid it? This is during runtime

[sand shore]

@true marsh it is warning C++ folks to not use it. Most of the time, BP stuff can be used from C++, but in this case it isn't a good idea

[true marsh]

Ahh cool, so its fine to use in blueprints?

[sand shore]

That is the same function that you should call from BP (as opposed to making your own callable add component)

[dawn gazelle]

OnDestroyed gets called to wrap up anything you need on the actor being destroyed. The next frame, it's gone, so any latent activities or timers will stop.

[true marsh]

Perfect thanks

[dawn gazelle]

If you're looking to do some additional things with an actor after it's been destroyed, you probably don't want to destroy the actor yet - you may want to hide it, disable its physics, etc, and then do what you need and then after you've done all that you want to, you should destroy your actor.

[vocal urchin]

Also trying this method to get the thing to spawn properly...I've used positions and rotations a gazillion times. Is there something special about Niagara? I printed out that transform too, and it is what I expect it to be.

[late shuttle]

I've been having the same problem.

I've had to attach the niagara system as a component of another actor, then spawn said actor.

[vocal urchin]

When I do that, I can't even see it at all. It's like it's not even there.

Seems others have had this problem too, and of course the reddit post goes un-edited 😄

I also notice that if I just drag the system into the world, it's still spawning at world zero

[maiden wadi]

@vocal urchin Sounds like your emitter is set up to use world space coordinates or something and ignoring it's emitter's location.

[late shuttle]

Actually, checking some BP, I have one working as "Spawn System Attached"

Then I'm taking a reference of the spawned niagara particle and force activating it.

[vocal urchin]

I guess this is now a Niagara question, but for the sake of just getting this working, do you know where to set that? This is like "hour one" of me using Niagara lol

AH, got it. Nevermind

Big brain in action

Now why that's not set as checked by default seems like a bit of an Epic goof.

Because it's entirely counter-intuitive.

[sand bloom]

hey can someone tell me why i'm a idiot, I have a object that drops when you stand on it, but here's the kicker it's supposed to get back when you stop touching it

seemed simple enough..

not sure why it won't go back

it drops fine

[maiden wadi]

@vocal urchin That setting will just make it local and allow you to move the particles with the emitter. More likely you need to check your spawning parameters.

Look for something under Particle Spawn. Usually a location type like Sphere Location. In it it'll have a variable that is your spawn location.

[sand bloom]

i'm guessing I can't use the value of 0

maybe a zigzag will work

nvm it didn't

welp i've tried everything i can think off besides just dropping timelines

but it should work

[maiden wadi]

This will spawn it at 0,0,0 in world space with local space checkbox unticked.

This will use the emitter's location.

[vocal urchin]

Hmm, actually I do have it checked.

Although i'm not sure why mine looks different from yours

[maiden wadi]

Is this the only location function in the emitter?

[vocal urchin]

I believe so?

[sand bloom]

Is there any reason why a timeline wouldn't reverse properly

is it because i'm starting from a vector of 0 value

and when it reverses it won't do anything because of that

addrelative location

I tried that earlier but all that does is drop it a little bit instantly for some reason

oh wait

I need to drastically increase my value with this node

Thank you it's doing something now, it automatically goes back up instead of waiting until the collision ends but this is progress

could be because it's only updating the rock location and the collision box even though the collision box is parented to it

fixed it 😄 thanks a lot dude

[faint pasture]

@sand bloom don't add relative, set relative

[sand bloom]

DSA told me the same a few min ago and it makes sense yes it fixed my issue 😄 Thanks for trying to help dsa beat you to the punch haha

[dusky topaz]

Is there something among the lines of an event dispatcher that allows me to define when "an event of this type" is supposed to happen, and have the remaining logic after the call wait for the called event to report back that it's finished?

[dawn gazelle]

That's what binding to an event dispatcher is. You call the event dispatcher when that event is supposed to happen.

[dusky topaz]

Yeah, but event dispatchers don't have the ability to control when the remaining logic after the call executes

[faint pasture]

@dusky topaz callback?

Or another dispatcher

Or just a custom event. What's the use case?

[dusky topaz]

Basically I have several different occasions where buffs might trigger, as an example, some trigger at the start of a units turn, so I want the animation and effect to finish before the player is shown the action menu

[maiden wadi]

Sounds like a good use for a view manager.

[faint pasture]

Or just have the end of then phase always be like 2 seconds and call it a day

Oh ya nvm it's per unit

[maiden wadi]

I find that things like that are best handled with a manager. You're going to end up with a lot of complicated views. Let the manager get the current state, or let stuff say "Hey, I'm doing this, don't display that stuff", and let it set up the view to the player. Your game logic will stay much cleaner.

[faint pasture]

Would that be what I've made by making my menu UI be a state machine?

Or is it something different

I don't have OpenMainMenu, I just set MenuState to Main

[maiden wadi]

Pretty much. In this case you'd probably have his buff thing get the manager, make it set the view to animationinging or something which removes UI and might set the view target to a camera, then on animation finished, set the view back to the last view and any other buffs can do the same in a row.

Multisphere trace from the cursor, and filter your results is probably going to be the easiest.

[faint pasture]

@swift pewter MultiSphereTrace, select closest

That's what I do for E interaction. Get actors with interface, select based on closest and most in front.

Ya sphere center

Uh why are you doing this every frame?

Is it meant to continuously choose target?

[dusky topaz]

I suppose this could work, I'll give it a go

[maiden wadi]

You don't need anything from the trace except the actors. Just get the actors and dot product their direction from the cursor direction.

[faint pasture]

Wouldn't you just use distance? Why the dot product

I think his is like a top down operation

Center and center

Used to have to move it like 1 cm but I think you don't anymore

[maiden wadi]

Yeah, fair. Distance is probably safer for that. Was considering for like distance from center of screen.

[faint pasture]

@swift pewter if you're a speed freak use distance squared for that sweet perf. Saving cycles one cycle at a time.

[lyric onyx]

Hi, I'd like some help about the "Add Math Expression" node.
I'd like to put the formula below in but I don't know how to deal with Square...
Here is the formula : X * (Y^Z)
To explain the context, I try to programm a RPG and this formula stands for the Damage.
X = Base Damage of the Spell.
Y = Scaling (in %)
Z = Level of the Player.
For instance, my Player is level 98, he uses the Spell which has 100 Base Damage and 6% Scaling per Level, the expression should be :
100 * (1,06^98) = 30.198
Can someone help me?

[dawn gazelle]

(X * (power(Y, Z)))

[lyric onyx]

(To myself: Sh*t... it was that easy?!)
Thank you very much

It works now, thank you again

[azure bolt]

hello does anyone know how I can set the rotation of the rod properly?

The rod is attached as a child of the wheel called 'bolt', and i've been setting the rotation like this, I've tried lots of different ways but none seem to work

[cinder shell]

hey guys! Can someone please tell me why does blueprint are trying to accessing "Target Actor" variable even if Select boolean is set to False? Receiving "Accessed None trying to read property" error anyways.

[dawn gazelle]

It still gets evaluated.

[cinder shell]

ah.. no way to skip it? Only with regular branch?

[marsh mountain]

hi guys i want to make a widget with a button and by pressing that button i want to rotate some specific mesh in other BP. I found that a dispatcher is a good way to go on communication between BP, but what was looking easy at beginning at the end i found confusing and not working. I don't know how to interpretate that issues from log any suggestions how to fix that will be much appreciated.

[dawn gazelle]

Pretty much. IsValid may be better if you're wanting to avoid using TargetActor without having to set the boolean at all.

[fiery swallow]

What's the point of tracing twice?

[dawn gazelle]

This Kuchnia 01 Poprawiona Drzwiczki object is not defined. You may have created the variable to contain a "BP_Kuchnia 01..." , but you have not set its value.

[fiery swallow]

There should be outhit hit actor

[placid wren]

I am trying to create a multiplayer options menu, if i have my blueprint like this it will work but my camera will move until i press my left mouse button in the options menu. Is there any way I can fix this without pausing the game, if the server pauses the game other players will teleport back into their old positions after the host returns from the menu.

[fiery swallow]

yes

[burnt nest]

I think you're looking for "Set Input Mode to UI", then when you close the menu you do "Set Input Mode to Game" or Game & UI

[placid wren]

ok, i will try

thank you so much worked instantly

[fiery swallow]

I assume that's to avoid fat fingering, That's one way to do it I guess. What I did was wait 0.5 seconds before setting target actor back to null

So once you hovered the actor and then clicked LMB even if you missed your left click you still had x amount of time to use an ability on the last hovered actor before it went null

IMO that's better then line tracing twice but it's not like line tracing is a slow operation

[cinder shell]

@dawn gazelle I see.. Thank you, my friend.

[fiery swallow]

I did a sequence

on event tick

This is what it looks like on event tick in blueprints

https://gyazo.com/1d0e3b10ab068124eee23d6478b81543

[burnt nest]

Just a tip, avoid using tick as much as possible. If you're just trying to click something, you should really only do what you need to do when the player clicks. Running a sphere trace every single frame is not great practice for performance.

[burnt trench]

Hello people. I need some help in figuring out how to make my player movement

[surreal peak]

Make sure not NOT mark those RPCs as Reliable @fiery swallow

[marsh mountain]

@dawn gazelle any tip how can i set some value you was talking about ?

[fiery swallow]

I would recommend this anyway because unless it's imperative to be running 2 line traces every tick It's probably not a good idea

[surreal peak]

You need to actually ask a question.

[burnt trench]

I'm making a player ship for an infinite runner

yes

Using the in built movement code

but this doesnt move my ship

[fiery swallow]

@swift pewter So the best thing you can do is have the cursor line trace on event tick and only once it hits or is close to an actor allow the second line trace to start. That would be least expensive thing I can think of

[burnt trench]

it stays still

even if I crank up the scale

[burnt nest]

Make sure you're actually possessing the ship, and not the default pawn. Make sure it's set to "moveable".

Put a "Print String" after your movement nodes to see if they are actually firing.

[burnt trench]

it is firing, it is set to moveable and I have set it tp pawn in my custom game mode

and made the GM the default for the project

no overriding Gm for the level

worth mentioning that I am using a static mesh and not a skeletal mesh atm

[dawn gazelle]

When you spawn the object, you get a reference to it.
If it's something you dropped into the world, you can get a reference to it by using something like Get Actor of Class (just don't use it for everything, and never on tick)

[burnt nest]

You have not connected the axis value for MoveForward. Though the scale is set to 1.0, so it should still move, but still!

[surreal peak]

Actors in the World can also always be setup to get something that can register to

E.g. a Component on the GameState or GameMode with a reference or array of references

[burnt nest]

Static mesh is fine, it doesn't need to be a skeletal mesh.

[burnt trench]

yes Axis value not being connected is intentional

[surreal peak]

BeginPlay in the Actor that is in the World can be used to access that Component and give you an easy ref

[burnt trench]

because I want it to keep moving without input

[burnt nest]

Could you try depossessing (F8) and select your ship and look at its position, see if it is changing at all?

[burnt trench]

it isnt changing at all (not even decimal values)

[burnt nest]

Wait, my bad.. you have to give it input for it to change still

Even if the axis value isn't connected

[surreal peak]

Axis should tick without a connection

[burnt nest]

Yes

And yes, that is true

[surreal peak]

Correct, endless runners, at least in UE4, should move the level, not the player

In UE5 you can probably can away with it

[burnt trench]

I will do that but the problem is I still wonna move the player in atleast the direction I'm facing sideways atleast then

I connected the axis value and still doesnt do anything

doesnt move an inch

[burnt nest]

Oh and make sure it's not stuck on some collision.

[burnt trench]

I just have 1 flat plane static mesh of empty map. Pretty sure its not stuck anywhere

I'm making the flying project and trying to see what I could do to fix it

interesting. The flying template just uses addactorlocaloffset to move

[modern wolf]

what does compile actually do?

yes

[fiery swallow]

You should print out the distance yourself to see what it's returning

[dusk flame]

What kind of resources do we have to validate BlueprintFunctions (from a BFL). I want to throw errors if input fields are left blank.

I found some old forum posts (with no answers) on this topic.

[modern wolf]

so if i don't compile it can still run, but it will need more time and resources?

oh ok

thanks

[dusk flame]

Even in PIE, blueprints are compiled afaik

[burnt nest]

Your loop is going through all hit actors, and your "Target Enemy" will be the last one it goes through. It probably sets your closest one first, and then the snowman, as far as I can tell.

[dusk flame]

I mean, its compiled for develop target, not shipping, so probably some optimizations are left out (for example print nodes are left in).

But its still compiled

Isn't that button gone in ue5 anyways?

Sort of like the save-button in Google Docs 🙂

Its there for safe feeling lol

[blazing ridge]

How do you connect or snap 2 spline points?

[dusk flame]

Speaking of safe feeling, how can I throw a nasty error if somebody uses my blueprint function without passing in a param?

No way to mark the node is invalid on compile-time?

I mean I am doing this in C++.

Its a BFL exposed from C++ to blueprint

My understanding is this kind of question belongs in this channel, since its related to blueprint-exposed stuff.

[burnt nest]

I noticed that you're comparing the current Target Enemy to the hit actor now. Hmm.

[dusk flame]

I know I can mark function as Pure, but that is just a mess in this case since I actually want the Execute Pin.

*pure function would throw the errors for me 🙂

[blazing ridge]

Is there still no way in UE4 to snap spline points onto each other, or connect 2 splines?

[burnt trench]

so I have copied the code from the flying template

now it moves.
But it is flickering and camera is fixed. DOesnt respond to input

also, I noticed, the template doesnt have gravity

but my project has gravity

even though simulate physics is off

[teal marlin]

Does anyone knows how to change bone position with IK like when I grab an item and play the grab animation sometimes the actor I want to grab is not in the right place to were the animation is moving so is it possible to change were the hand is getting to each time I grab an item to the item location?

[burnt nest]

That should be fine. If you're now using AddActorLocalOffset, you're not using physics. Gravity on/off doesn't do anything without simulating physics.

[burnt trench]

default gravity is same

it does

if I set the player start in the air

it falls down

idk why

[burnt nest]

Then you're simulating physics on something.

[burnt trench]

only thing is capsule

its off on it as well

dont know why the ship is still falling like gravity is affecting it

[burnt nest]

And you're sure you're using the correct pawn?

[burnt trench]

Found it. there's gravity scale in character movement too

made it 0

[burnt nest]

Interesting 🤔

[burnt trench]

only thing left now is it doesnt turn left and right like the template does

The code is the same

now made it a pawn instead of a character

[shut hinge]

how do we do dialog audio and skip ? I don't know the logic to it.

[burnt trench]

nvm fixed that issue as well

[pine rain]

For those familiar with how Unity does it, is there an event in Unreal Engine Blueprints, which is called whenever the game is closing or when the actor is being destroyed by the game closing?

[trim matrix]

Is it possible to convert Unicode (e.g. U+0100 [Ā]) to Text in Blueprint? Or will I have to do it through C++? Basically, I want to set a Text Box to be a random Traditional Chinese Character.

[pine rain]

thanks

[marble tusk]

right click the spline point. There's a bunch of snapping and aligning options iirc

[icy dragon]

Unreal already support Unicode characters. It's just the matter of adding the font that support such characters.

[trim matrix]

Well, it doesn't seem to work in UMG, but I managed to get it working in C++

With UTF8_TO_TCHAR

[blazing ridge]

@marble tusk Thanks a lot buddy! I thought there was some hotkey you need to have pressed but this works just fine

[marsh mountain]

@dawn gazelle its working now, thanks !

@dawn gazelle but now i'm faceting another issue that branch is outputting true and false at the same time.. any ideas what it might be ?

[runic plinth]

Morning, I'm sorry to be yet another one asking for help but I googled for hours now and tried so many options. Im trying to cast to player pawn but it always returns null on the debug. Also I was trying to adapt this animation blueprint from the Shooter Game Level and now the original one doesn't work anymore Im guessing I broke some references somehow. Any ideas on how to fix it?

[unkempt torrent]

Can someone point me to a tutorial for physics controlled AI?

[lunar holly]

I have a question about the score in a game. I use a score variable in my Game Mode. Should I write the score code in the player Class and then send the score value to my Game Mode? Or should I write all the score code in the Game Mode Class, so I Cast to the player from the Game Mode?

[icy dragon]

You can send the scores to the Game Mode.
Though if it's single player, I'd prefer Game Instance.

[lunar holly]

@icy dragon What is "Game Instance"?

[icy dragon]

Game Instance is a Game Framework class that persist as long as the game executable is running.

[worthy frost]

not just client side..

[icy dragon]

Corrected.

[worthy frost]

its basically a singleton that lasts from application start to application end (client and server)

or from PIE start to PIE end.

[lunar holly]

So it lets me store variables. And those variables are kept even if I go to a new scene?

[gentle urchin]

Yes

[lunar holly]

okey

[icy dragon]

It's very useful to store player side variable you want to serialise for the save data.

[olive sedge]

Is it possible to extend Spline or SplineMeshComponent? I want to add additional properties for the spline points

I need them in the construct script so I can define the roll for each point

It is possible to set the roll on AddSplineMeshComponent but not in the viewport/editor

[celest sleet]

hey hey, got a veeery basic question here, it'd be great if someone could give us a super quick hand or point me to a good article!
I'm doing a ue4/fmod tutorial project, and I'd like to get the distance between a reverb zone in the level, and the player character. The player character spawns when the game starts though, so I don't know how to reference his transform in the level blueprint. Dragging an instance of him in to the level and referencing that is no good, because then when I delete it the reference breaks.
Would someone mind letting me know how I can set up a reference to the player like that? I'm guessing with a "if actor exists, get transform, promote to variable" kinda thing, but I've no idea and I've been digging around online for quite a while now

TL;DR How do I reference something in the level blueprint which isn't present in the level before starting the game?
Thanks very much 🙂

ooo that might do the job

really sorry to pester with this simple stuff, but do you know how I would not proceed and try again next frame? I guess I need some kind of "if valid" or "if get player character is not null" check

Hey guys i have set up a simple ai move to function

But whenever my ai hits my player it stops following

[trim matrix]

i need help with one blueprint

[loud cipher]

i then have to re engage the ai by overlapping a box collision

[trim matrix]

can some one help me ?

[dark crow]

No.

Jk, just ask, don't ask to ask

[dark crow]

That's most likely a Pure Getter, if you wanna make one yourself, you create a Function, have just an Output Var and mark Function as Pure
You can have logic that leads to the Output ofc

[vocal kestrel]

Howdy, so odd question but is there a good resource for learning Project Managment systems for unreal? In unity i coded Manager of Manager systems, which sat in scenes and tracked/filtered broadcasts and events to everything. npc controllers sent info to managers which actually did the code, managers tracked aysnc save progress, ect ect. Was super useful as unity didn't have any cohesive management systems like that.

stuff like if a player is shot, they don't do the damage calc they tell the Player Manager that they were hit. all player does is hold their hp. the info's passed to it and then it runs the LoseHealth code and sends the new values back to the player. fully disconnected logic and data so slotting in new anything was trivial.

however i'm inclinded to recreate it in unreal but i'm... uncertain what Good professioanl scene/project management looks like in this engine as it's clearly different (i mean wtf do you DO with level blueprints??)

So stuff like writing systems that check everything's properly loaded in, checking that all npcs are where they're meant to be, checking that the weather system is updating properly, this and that. stuff that isn't very sexy but cohesive projects kinda need as a backend. unity doesn't do much for you so i have no idea how much unreal gives you to work with.

[dark crow]

I don't see why you can't do that
Usually for common Managers it's just a BP Actor placed in a Scene with logic in it and you can have players or whatever interact with that Actor
Up to you to decide what it does, you have all the freedom

[vocal kestrel]

yeah, it all looks like it should work more or less the same. it's just something that isn't talked about much so it can feel like i'm missing something.

though a big question would be, what's the best use for the level blueprint if i inent to make as much of the code as generic as possible? is that largely for making sure managemnet systems and important stuff is spawned in?

[dark crow]

Level Blueprint just use for Level related stuff you don't want elsewhere tbh

Since as soon as you change level that's gone pretty much

And depending on the Manager, if everyone has a common one, you just place it yourself in the level

[vocal kestrel]

so prob good for holding level speicifc spawning information, or things like "on this map, fill in this var for how much hp you lose per second cuz it's a hellmap or somehting" ?

[dark crow]

I would actually have that as an Enum in the manager and change it myself based on the map or so, am not really a big Level Blueprint user tbh

[vocal kestrel]

yeah, i did it before by ensuring that unity loaded up with a handful of top-level managers that persisted between scene changed, and those kept track of different managers that different scenes needed, ensruing they all spawned in and loaded right.

[dark crow]

I prefer having everything self contained

[vocal kestrel]

that's fair.

okay, that's the gist of what i wanted to know and ngl was a big factor in my confusion; the actual purpose of level bp

i guess it's a very situational tool that yuo can take or leave

[dark crow]

The only times i used it was for playing music in the main menu and moving the camera around when i click a button in it with a direct camera ref

You could have logic in there for sure, but just think if it fits your situation since when a level change happens the code is not considered anymore

Each level has its own Level BP

[vocal kestrel]

yeah i can see putitng some stuff in the main menu bp being useful, as there could be checks/ect that you really only ever want/need done in that speicifc circumstance

fair enough, unity doesn't really have an equivilant to that and i spent 2 years in that engine every day. so that extra layer was throwing me

[dark crow]

Yeh, in the end think it like Unity, you create an Actor Manager, players talk to that and Manager executes the code in case

You can have Managers talking to other Managers too

[vocal kestrel]

that's def how i want to work, so yeah i'll see about getting that back up and going. the book i learned unity from REALLY pushed management systems early, and so none of the offical learning meaterial from unreal talking about this stuff has been weird.

[dark crow]

If you want the player to hold a ref of the manager since they'll only be one in the world for testing you can use Get Actor of Class and have as an input the Class of the Manager and hold it as a Ref then talk to it

If it's a Spawner Manager Ref is as easy as getting what Spawned you with an Exposed Var

[vocal kestrel]

how critical are event dispatches in that? i used alot of custom messaging systems to throw broadcasts events around in unity, so that a box could die and shout I DIE, which a hud manage rhears and says "oh i should go tell the hud to update itself".

event dispatchers sound ilke much the same thing (things sending info don't care about what hears it so things are less interlocked) and sooorta work the same way.

oh btw thank you very much for the info, it's actually been very helpful and i appreciate it

[dark crow]

You could yeh, i think there's many ways to do it, up to ye to find the best way that fits you :p

[vocal kestrel]

uhg, the best and worst answer at once 😛

but okay, i'll try out some of what you mentioned and try and replciate some old methods. good to know there's not some odd barrier in my way like i kinda throught there was.

[dark crow]

i have some pics of Event Dispatcher workings if you want

[vocal kestrel]

that would b elovely actually

i've gotten them working in a way i think i'd like, but it was a few tests last week and nothing as extensive as working them into any complex manager system.

[dark crow]

Dere

[fiery glen]

Subsystems are a nice way to have "managers" but they are C++ only afaik

[dark crow]

Pretty sure they are C++

But automatically exposed to BPs

[vocal kestrel]

yeah, that info is def useful. it's not AS flexible as the broadcasts i was using before, but i could prob make it work if i dug into it (ie have hte listener be some middleman node that sends info to various classes/things it's spawned/ect?) so that nobody really needs to know anything about what's picking up it's cries other than "we're sending it to a listener hub that'll handle the rest"

that sounds like it'd work

[dark crow]

iirc UE3 was using global broadcasts but trashed them for performance reasons

[vocal kestrel]

that does make sense, i was using some mutant version of C# events made to work in unity that didn't have the performance overhead that normal global broadcasts did. soem of my confusion is probably just coming from getting used to workin with this odd codebase.

but yeah normal global broadcasts for everything is a bad call

https://wiki.unity3d.com/index.php/CSharpMessenger_Extended
this thing, if you've ever messed with unity or such

[dark crow]

Event Dispatchers are mostly useful if you want one event to influence many different things

Example they made is if a boss dies and torches in the room turn off and door opens

All linked to the boss dying

[vocal kestrel]

that is what unreal recommended in their docs, yeah.

i guess i just had a really specific weird way of working and i did it for too long and it's kinda fuckin' with me :/

but okay that's a good point

okay, i'll... see about getting my mind out of the GLobal Broadcast mode and try to make some managers that'll handle the logic and just let things that need to talk to it have semi-genierc and reasonable ways to get/send that info without breaking if they're removed.

i have not

well i have like 3 C++ books, i guess if i really care that much it's not that big of a deal

yeah, i've been coding for like 5 years

But that's actually super good to know

i'll put subsystems on the list of things to learn sooner than later. managmeent systems, save systems, ect all seem like stuff you want to learn early cuz the later you impliment any of that the harder it gets.

oh yeah, i messed around with it a bit. not enough for anyting cohesive but it's good to see.

I've written like... two? two differenct save system in unity before

so iw as prepared to just do it myself

so that was nice to find

uhg

Yeah

Yeah, most of my fondness for unity is frankly from spending a year+ learning literally liek 300-400 differnet Store Asset toolkits, and learning how to weld together wildly differnet codebases

and by "fondess", i mean " trauma"

Unity is a neat engine but you need to spend so much time na dmoney on third party assets to fill in gaps in the engine that unreal already has filled.

It really shows that epic actually uses their engine to make and LAUNCH video games, and unity uses theirs as a testbed for cool tech ideas.

each team/studio that earnestly uses unity has their own special version of it that's suited to waht they need, as unity does really let you get in there and make engine/editor modifications real easy. so you can get soemthing smooth and very specialized

it jjust.... ya know, takes alot of time and frustation and it might not be worth it???/

regardless, yeah unreal's been... it's got it's own frustrations but it's def a better thing to work in for general 3d games. unity does handle 2d alot better, but hey dif tools for dif purposes.

[fiery glen]

Turns out never using your own product means nothing ever gets fixed

[vocal kestrel]

yeah, i firmly believe that you will find endless problems with your own tools the moment you stop 'developing' and you try to use them for something legit productive for 5 minutes

very easy to just let problems sit otherwise

[faint pasture]

I wish we had a 1st party ECS solution tho

[fiery glen]

ENTT/FLECS are simple to Integrate for backend c++ stuff

There's a marketplace plugin for a bp supported ecs

[faint pasture]

Godot has some great ideas too. I love the "it's scenes all the way down" philosophy

[fiery glen]

But yeah gameplay code in ue4 is a little old fashioned

[faint pasture]

I wonder how UE4 runs as good as it does. Does it do anything internal cache friendly handling of things or are we just thrashing the cache all day but making up for it with fast processors?

[fiery glen]

Animations are done internally with crazy ispc async stuff etc

Moving actors ain't cheap though

[vocal kestrel]

i mean i got into unreal largely to make films and do previz, as unity has the functionality but just has No documentation or real support.

i mean you can do it but good luck figuring anything out.

meanwhile epic's got like a new behind-the-scenes minidoc every week or so about how X film used unreal to make Y, or how Popular Film was made 100% in unreal for previz before filming

while it felt bad, switching engines wasn't that hard of a choice really :/

i mean realtime rendering for production is rad

hell even some anime studios are using unreal 4 these days for their backgrounds/blocking/ect. wild stuff

[fiery glen]

He's doing GPU shader anims, right? No way regular anims will beat that

[vocal kestrel]

ngl, now and agian i plan to do a Dynasty-Warriors esk big army beatemup style game, but then i really consider all the Smart People Stuff that would reeally go into putting a fuckton of dudes on screen to wallop through, and i chicken out.

[covert arrow]

whats the best way to line trace for a fps gun, would line tracing from the muzzle for the start then getting the player camera forward vector work?

[spark steppe]

yes but no

you would better line trace from the camera, because that's what the player expects

Hey guys, i'm playing around in UE5 and am completely new to UE as a whole, why can't I see the keyboard input I set up in the engine settings, inside my blueprint?

https://i.imgur.com/ADV48CY.png

https://i.imgur.com/yq596KR.png

[burnt nest]

What type of blueprint is it?

[tawdry charm]

An actor blueprint

[burnt nest]

Try a pawn or a character. They can handle input.

[tawdry charm]

How do I change that, it doesn't seem to be an available parent class?

[burnt nest]

Create a new blueprint, select pawn as the base type.

[tawdry charm]

https://i.imgur.com/qKf7syJ.png

[burnt nest]

Hm. Silly UE5 doesn't have it as a common option. 😮

Click all classes at the top then. 🙂

@burnt nest Pawn isn't on the list in "All Classes"

[burnt nest]

Really? 👀 It should be a sub class of Actor.

Unless they were completely annoying and renamed it in UE5. 🤔

[tawdry charm]

Yeah Maybe

[burnt nest]

Oh. But it says Actor Component at the bottom?

Is your blueprint an actor component?

Right.

[tawdry charm]

Thanks Guys 🙂

Time to work out the best way to change the rotation of an object like this

[covert arrow]

i asked this question yesterday but no answer how do you make input frame dependent

[burnt nest]

Hmm.. I'm not really good enough at vector math to help with that one. 😦 But if you're using the movement component, I feel like there should be some built in stuff to let your actor slide along collisions.

[olive sedge]

well, the thing is I don't want to use the movement component, I couldn't get it to feel right

I had this before but never felt like I wanted it to

[burnt nest]

Lorash to the rescue

[olive sedge]

that pink is the normal vector

[burnt nest]

What about the yellow one? That seems to stick straight out.

[tawdry charm]

Smallhead, how would I go about changing the rotation of an external DirectionalLight?

[burnt nest]

Ingame, from a different blueprint? GetActorOfClass, and grab the directional light.

[true marsh]

I'm attaching a scene component from one actor to a scene component of a different actor and it works. But when the original actor is destroyed so is the passed scene component, is there a way to prevent this?

[burnt nest]

Sure; detach it first.

[burnt nest]

Sorry, I sort of get what you mean but I also sort of don't. What is it you want to do? 🙂

[olive sedge]

@trim matrix it's easier said than done.. how do I rotate the 90° towards my movement/facing vector?

[tawdry charm]

https://i.imgur.com/zAhM0rx.png

Any idea why it's not working?

[burnt nest]

Is the directional light set to moveable?

[tawdry charm]

https://i.imgur.com/dZdBYm1.png

[covert arrow]

@burnt nest nvm i wanted to ask about a modular health component

should i keep the data in the component itself or attach a structure to the component

i'm also using an interface to apply damage

[olive sedge]

@trim matrix that's some pro shit. I'll try it and report back

[burnt nest]

That's really up to you, Moldy.

[burnt nest]

I have to admit I'm at a loss. Maybe try add actor world rotation instead.

[stiff linden]

Trying to do a pause menu--found the "execute while paused" tick box on my InputAction node, but it's still not working, I think because as part of pausing/opening the menu I do a Set Input Mode UI only, and the OpenMenu action mapping i have is technically a gameplay thing.

what's the workaround for this? I got it to unpause with a simple inputkeydown check in the menu widget itself but that's messier than I would like (and was executing on the first frame the menu popped up)

[burnt nest]

Oh, it also could be that it doesn't save the result from BeginPlay until you press the hotkey. Try saving it as a variable first.

[olive sedge]

@trim matrix when you say clockwise... 🙈

it would mean around X in + and -?

[tawdry charm]

It's getting the right actor now but it's not setting it's rotation on keypress:

https://i.imgur.com/HGe4gEj.png

[burnt nest]

Hmm.. since I suggested the Input Mode UI thing, I feel obligated to fix this. 😅 Perhaps in this case you'd want a bool set to true when you open the menu. Put a branch at the start of your other inputs, and check if IsPaused is true. If it is true, do nothing, if it's false, execute as normal.

[olive sedge]

like this? https://i.imgur.com/Q1WmlpT.png

[burnt nest]

Hum. Could you screenshot the event graph now?

[trim matrix]

hey guys added grenades to my game but they seem to only hurt me or enemies about 25% of the time

this is the logic

i can stand my character within the radius and it seems pretty much random whether it hurts

[burnt nest]

I have no idea to be honest, Wonder Boy. Looks like some debugging practices may be in order.

[true marsh]

Oddly thats not working, even though the return is saying true on the attach. Printing the owner after the attach and it is staying the same/not updating. I'm still troubleshooting.

Might be related to a by-design oddity? UE4 bug tracker UE-20417. I’ll double check soon

[trim matrix]

yup i'm reading on various stuff that could be the issue

DEP channel visibility etc

[shut hinge]

got an issue i don't know how to resolev. Movie is on USB F: drive, so the game won't play it unless the UBS F:drive is connected, how do I get the movie to play in the proper drive, it sayin it can't package it unless its in the movies directory, but it can only read it from the F Drive...

[stiff linden]

you might be thinking of another person with the input ui thing--i just showed up haha.

I can already tell the game is paused by IsGamePaused. I'm not checking inputs with key nodes like IsInputKeyDown--I'm actually using Action Mappings and Input Axis Mappings for input--which seem to be suspended when Input Mode is UI Only. I want the Open Menu action to be exempt from this, basically, but i can't find a setting for that. Hoping I don't have to handle this one key press with entirely different bp scripting than the rest haha

[burnt nest]

Oh, really? 😄 Someone was making a pause menu earlier today, and I suggested they use Input Mode UI, haha.

[shut hinge]

Anyone done a skip audio and text dialog tutorial yet with a data table, am looking for one.

[tawdry charm]

https://i.imgur.com/knCxJfq.png

[burnt nest]

I figured you use axis mappings; that's fine. You'd put a IsGamePaused check after that. Then you could just use Input Mode Game & UI instead, and manually set which hotkeys will execute when the game is paused.

[burnt nest]

Looks about right... if you rotate the light manually in the editor, it works?

[tawdry charm]

Yeah

[burnt nest]

I'm just not sure you can allow a hotkey to work when game mode is UI only. I don't think you can.

[tawdry charm]

it's the input not firing

[burnt nest]

Okay um, have you placed TimeChange in the level and checked that the hotkey event is firing?

[tawdry charm]

I've changed it to mouse3 which is default and it's still not firing

[olive sedge]

@trim matrix yes, I got that, it works (just one direction for now, I'll figure out the dot thing later)

[burnt nest]

Right. Maybe you should put this functionality in the player?

[stiff linden]

hmmmm....i guess all my other input events don't have "Execute when paused" checked so I could just.....not use Input UI Only in the first place and not even change anything...

[burnt nest]

Now that's a bighead move.

[stiff linden]

🤔

eyyyup

just deleted it and it works lmao

i think the tuts i saw that made menus with Input UI Only didn't even allow you to unpause with a key press? Just a button in the menu itself

so i was kinda under the impression you need to do input ui only to have a pause menu in the first place...

I guess i need it to click on the menu stuff, but i can do Set Input Game And UI for that and set back to gameplay on unpausing.

[burnt nest]

If your game was multiplayer and the game didn't pause when you opened the menu, you'd not be able to rely on execute when paused though.

[stiff linden]

tru

not the case here tho so lucky me

[burnt nest]

I think you should use both game and UI, and just set show cursor to true.
Otherwise I think it's to do with these settings regarding when to "capture" the mouse.

[prisma stag]

Ill take a look at that however I previously had it set to game and ui and had it show mouse cursor but it never worked.

[olive sedge]

@trim matrix this works really well as long as the wall is not rotated itself..

Did you add a socket on to your mesh called muzzle?

nope

its a static mesh

[dawn gazelle]

That's fine

[dawn gazelle]

Open up your static mesh from the content browser

You should end up in this view.

[restive dagger]

yeah?

[dawn gazelle]

Bottom right - create socket. Then you want to position the socket using the manipulator to put it approximately where you'd want to consider something to come out of it. Orient the red manipulator so it's pointing towards the direction the bullet would travel.

Then when you want to reference it's position or rotation, it's a matter of getting the socket:

Hey there, not sure if this is the right place to ask (and sorry if it's been asked many times before, feel free to send me elsewhere), but I'm trying to create a settings menu of sorts, and the selected value returns to default whenever I close and reopen the widget. Is there anything in my blueprint I'm missing so that I can save that value for later?

[keen hearth]

I'm looking to setup a host of mechanisms to place in the world, and for them to contain the logic and player animation to interact with them. So they get the player character and run a button press, or lever pull etc...
When I do this using the Play Animation on the mesh to breaks all future animations on the character leaving them sliding around as they move. I guess this is the wrong route to achieving this. Can someone point me to info on what I should be doing here. Ideally from within the mechanism actor and not resorting to the animation blueprint and state machine.

[keen hearth]

I think the widget is being destroyed. So you want to store information outside and then let your widget read it. A tip is to not use your UI to store any game critical information, just think of them as being ways to visualize existing data.

[full hare]

I am making a tower defense game and i am rn setting up upgrading towers but i need to make it so when it gets upgraded (a different actor spawns) so the older one gets deleted i tried using like casting and destroy actor but it for some reason didnt work any ideas ? any help is welcome 😄

[dawn gazelle]

How are you "closing" and "reopening" the widget?

[narrow kelp]

@full hare I'd consider changing the artwork on the actor instead

[full hare]

Like having everything on 1 actor ?

and just adding and removing stuff ?

[dawn gazelle]

Have you tried play montage?

[narrow kelp]

If that makes sense for your case. I imagine that when a tower gets upgraded, most of its behavior is still the same

with better damage and new artwork, or something like that

[full hare]

yep for example it will give more money and etc its a school project and i have only like 2-3 days to do it so there aint much details and as long as it works i dont mind any solution for now

are there any tutorials for that on youtube ? since i am not too sure how i should google it ?

[narrow kelp]

Not sure, but you can look for general programming in blueprints

[crimson saddle]

I need some help. I have an array of structs, each struct has an array of integers. I need to add integers to the array in one of my structs, but it doesn't seem to work at all. I have no idea why. Functions before and after the Add entry fire, but it seems like it doesn't actually do anything.

[full hare]

I will try to find it thank you for help

[wet notch]

Pressing 'E' to open and pressing 'R' to close.

[dawn gazelle]

What nodes are you using that actually close and reopen the widget?

[wet notch]

I did see that mentioned when searching the UE forums, but since I'm still learning a lot about the engine, I wasn't completely sure how to achieve that 😅

[dawn gazelle]

So what you are doing there is creating a widget, and removing it from the view port each time you open and close it - the values would not be retained as you're creating a new instance of the widget.

You have two options:

1. Don't create a new one and remove from parent each time. Instead, IF the widget is valid when going to open it, set the visibility to "Visible" If not, create it. When going to close the widget, set its visibility to collapsed.

2. Store the values you're concerned about externally in a different blueprint. If it's for settings, then you may want to consider putting the value in a save game object, and on the "Construct" of the widget, you would load the values from your save game object.

[restive dagger]

I switched it to Play Anim Montage passing in the character. It doesn't play an animation though. In the preview the montage works fine, but nothing in game. I checked the return value which returns the correct animation time, so it is there. I'm guessing the montage isn't overriding the main character anim blueprint.

[indigo bough]

Hey folks,

I have this work-in-progress possession setup, where up to 3 players can interact with a gun, and each be given a different role in the operation. The plan in future will be to have a set of animation sequences that play out as players run through the process of reloading/firing.

Anyway, that's just the context. My question is in relation to the possession. Currently, my controller is possessing one of three 'gun crew slot' pawns which are child actors of the gun. At the same time, I switch out the old pawn's animation blueprint to perform the 'animation' appropriate for their 'gun crew slot'

Because I have disabled auto camera management, the player still sees through their original pawn's eyes, which is intended. However, I still want to provide the user some ability to turn their head with the mouse x/y movement.

TL;DR: How would I let the controller send input to both the current 'crew slot' pawn AND send the mouse x/y input to their now unpossessed original pawn.

[blissful cosmos]

Do I need a playercharacter? Is there a reason not to only use the PlayerController when there's not really a pawn to control? I want to work on an RTS style game

[unreal wing]

yeah i think you do, RTS game would be cool good luck with that!

So I have been trying to make a text animation play when ever the player picks up a coin. However with this blueprint, every time I pick up a coin, the small UI animation on the coin counter wont play. any thoughts on how to fix this?

[burnt nest]

Yes, you need a pawn. The pawn in an RTS game would contain the camera, for one.

[indigo bough]

As an additional attempt, I tried this, which successfully casts back to the pawn, but the actual Add Input doesn't happen.

[placid magnet]

Hello! Im used to unity development where attributes and stats of a character are visible during runtime in the editors detail tab, when using the attributeSet type I cant seem to find a way to view my characters current stats without using a printfunction or a widget display. Is this intended? Is there another way I can expose this data to become visible in the editor details tab?

UPROPERTY(EditDefaultsOnly, BlueprintReadOnly, Category = Abilities) specially with EditDefaultsOnly

hmm ok

[keen hearth]

That resolved it. Thanks. I've never used Anim Montages before and I didn't realise that they needed linking via the Anim Blueprint as a Slot.

[placid magnet]

@trim matrix thanks

[faint pasture]

I would give the gun crew slot Pawn a camera, and have it attached to the camera attachment point in the character head. Then mouse input when in the gun pawn sets local rotation

[indigo bough]

Interesting, so attaching the second camera to the old pawn's head. I will try this. Thanks!

[mellow lava]

Has anyone had success mutating VectorCurves at runtime? RootMotionJumpForce seems to require it for downhill destinations

[loud cipher]

Hey guys for the on component begin overlap

This only applies when a component begins to overlap

Not when a component is already overlapping

How can i make it so it still applies if the component is already in the overlap

e.g. if they have spawned in the overlap

for it to still apply

Nevermind

Solved

Simple check if it is already within the overlap

[spark steppe]

@indigo bough have you checked if the original character still has any controller assigned?

[indigo bough]

Hmm, good point. Would it need one?

And if so, which controller? Can you have a controller that isn't a player?

[narrow kelp]

try setting focus to your widget

[spark steppe]

well, guess it needs one if you use add yaw/pitch input

and i don't know what happens in your scenario, would debug it by getting the controller from the player after possessing the weapon pawn, and print its displayname to the log

[indigo bough]

Okay, thank you! I'll take a look into this 🙂

[frozen needle]

Hello. I have this base for teleportation with teleport location rotated on left and right mouse button, but I'm not sure how to store an array for it to work properly. What should I do?

[spark steppe]

an array of what?

[frozen needle]

the teleport points

that are placed on the level

[spark steppe]

you can use getAllActorsOfClass in your beginPlayEvent to populate your array

get all actors which are of the teleportpoint class, and use it to set your array

[frozen needle]

Now it works but it's skipping one teleport point with the error. What could be the issue?

what I have right now

[dawn gazelle]

Promote the array from Get all Actors of class to a variable and use that variable where required (where you're currently hooking up all actors of class' output to).

The other issue is that you're assuming there's at least 3 elements in the array. This message "Accessed None" means you're attempting to get a reference to a null pointer - there's nothing set in that value and the "CallFunc_Array_get_item_2" indicates how you're referencing the item - you're trying to get an item from an array at index 2 which means there's nothing at the third element in the array. This all means that you're getting no value returned at index 2 (array item #3).

[prisma stag]

Hello, Ive been having a problem with the cursor and clicking in my game.

I have a menu that pops up and then you make your selection and then click on the ground where you would like that item to go. After some talking we found that settings the inputmode to only ui instead of both worked also keeping the cursor on the screen so you could see where you were clicking.

However, if you right click, it disables the mouse from influencing the camera and you must hold RMB to move the camera (which Im ok with), but now you have to double click to make your selection

[indigo bough]

Looks like has no controller, I just added a 'spawn default controller' into the possess event, and now it is controlled by an AIController class. I can obviously change that default in the pawn BP, but that seems to break things. 😦

Putting an empty controller class in there as the default works fine, but I'm still not able to get my input to register on the old pawn

[spark steppe]

you could probably attach the camera to the pawn that actually gets the real input on possession

and move it back to the character on unpossessing

but also just an idea, not sure if it would work around the issue

depends on how your camera/input system is setup

[dense citrus]

heya, quick question for anyone who can help, so, i'm trying to make a physics based bullet for my gayme, and each time i fire the gun, i have a "on begin overlap event" to trigger a particle and sfx. the issue is it seems to be VERY inconsistent, any idea why this might be?
(note, those blue planes are what i'm using to visually confirm the hit, combined with f1. and it's very odd cause the hit just wont register if i'm looking at certain angles or what have you.
the collisions for each plane is set too a simple box collision, and the bullet, and bullet hitbox is set to overlap all.

[frozen needle]

Thank you for the answer, unfortunately I can't figure out why it doesn't see the last teleport point of the array

[spark steppe]

show your current node setup with the changes you made

[narrow kelp]

@dense citrus In my experience UE4's collision just kinda sucks for small fast objects like bullets. If you want to make it better, you could have your bullets tick and do a line / sphere trace over the delta distance, then just set their position.

[dense citrus]

okay lel, thx

[spark steppe]

or do a line trace on shot and calculate the delay to trigger the effect

[narrow kelp]

Yeah if you dont need the bullet to actually travel, then just a trace is all you need

[frozen needle]

Here

[dense citrus]

eh, sorta, i'm making a game that will use the enviorment to affect the players, and the guns are going ot be more akin to tools then weapons, so i sorta want them to be cumbersome to use

[spark steppe]

disconnect and remove that for loop in beginPlay @frozen needle

and the set array elem, too

and in the upper branch you set the current teleportation point to the array length, that should be array length -1

[frozen needle]

@spark steppe thank you, that fixed my issue

[dense citrus]

okay, i'm having one more issue with my bullet thing

it's literally beginning an overlap event with the air

[faint pasture]

@dense citrus What is it saying it's overlapping?

[dense citrus]

ngl, i have no idea how to check. if you mean the trigger for it, it's "event on begin overlap"

i just see this and i'm like not supposed to happen

and it registers as a single hit

[faint pasture]

@dense citrus print the overlapping actor

What is it?

[crimson saddle]

Why won't my custom gamemode inherit functions?

[dense citrus]

i did object and it just says "box"

[faint pasture]

Then it's overlapping a box

[crimson saddle]

I have a generic gamemode class that all my others inherit from with things like saving the game but I don't see them as I would in another blueprint

[faint pasture]

What are the collision settings for the projectile?

[dense citrus]

overlap all

and i have no object in my scene named just "box" as far as i'm aware

[faint pasture]

Well yeah so of course it's going to trigger overlaps with like everything. Set it to only overlap the things that you want it to overlap

[faint pasture]

You probably have an object with a box component. That trigger box is attached to something

[dense citrus]

ah, yeh, fair enoguh, i'll do some more tigging then thx

[faint pasture]

Anyway you probably don't overlap all with a projectile unless you want your projectile to trigger triggers. Try overlap only Pawn for now

Learning how how the Collision system works is one of the best things you can do. It's incredibly powerful

Like if the projectiles meant to hit terrain and walls but overlap pawns, you'd give it a custom collision profile that ignores everything but blocks WorldStatic and overlaps Pawn

[dark crow]

Wat

[faint pasture]

How big is the array?

I mean just get(0) thru get(4) and promote results to variables.

Get(index) just gets that one element of the array

What exactly are you trying to do? This is a very weird question.

[dark crow]

Neato, still confused

But am glad you figured it out

[shadow saddle]

chaos physic only available in 4.26 ?

[dark crow]

I think so yeh

4.26+

[rough blade]

does a ticking bp component increase frame calculation time even if it isnt doing anything?

ie - static mesh

[icy dragon]

Actually 4.23+, but Chaos Physics isn't production ready even in UE5.0 Early Access.

[dry pewter]

Hello everyone

I have this, it's working as intended, now i need that the map variable (Weaponinventory) to be substituted with one of other 3 map variables (int key and name value too) so i don't have to make 4 of the same node procedures with each variable. Can i make that?

[keen hearth]

I don't know if that gets cleaned up during build, if nothing is hooked up. One tip I got was to go into your project settings and you can set Tick as being off by default. That would be better practice as then you'd only switch it on purposefully.

[dawn gazelle]

You can use a select node

[dry pewter]

Didn't know that one, going to check it now

[dry pewter]

Yeah as the value will come from "wich position is the menu cursor on/30" (as the options are 30 units away one from another on Y axis) it'll work as a charm

[scarlet arrow]

Hey guys, i have a problem in UE4 BP, i want to know how i can display a final score on the winning screen, the concept is to display how much time the player took to go from point A to point B, something similar to this example

[dry pewter]

Make the score be stored on a variable, then on your widget bind the text after "Score:" to be that variable value

[dry pewter]

Seems to be doing the work, now i just have to tweak the other places where i needed that and test, Thankyou!

[scarlet arrow]

@dry pewter

[dry pewter]

I see you are counting seconds and minutes there

[scarlet arrow]

i basically have two widgets, one for the game and another for the final score

[scarlet arrow]

the one for the game only has a timer and the second one looks like this

[unreal wing]

nice

[trim matrix]

hey I have a question i am spawning a blue print object that is a text render i have got everything working except the issue of multiple of the text renders popping on the screen when I put another string in the widget text box. I have tried destroying the actor when you destroy the actor with out a delay it destroys everything but when I add a delay it doesnt do it. I even made it where I have tried destroying the actor in the blueprint it is spawning in general with a boolean and making it so when the widget sets the boolean to true the code should print a string and destroy self but what ended up happening was it printed the string but didnt destroy the actor i eventually scratched that and made so that i got all actors of class then as a return destroy that inside the blueprint but that did nothing

[dry pewter]

go on

[dry pewter]

So you basically need to destroy the previous text before popping the new one?

[trim matrix]

ok ill try that

[dry pewter]

@dawn gazelle Sorry if i botter you mentionning personally.
Can you "set" a variable result of the select node?

[dawn gazelle]

I think this may be what you want?

Plug in the return value into Target, and the value you want into value.

[trim matrix]

i hate how the solution was so simple either way thank you @dry pewter

[scarlet arrow]

@dry pewter hey i already figured it out i basically copy what i had, grab the same code i had on the game widget and place it on the end screen widget

[dry pewter]

Exactly! So much i don't know, Thankyou!

[dry pewter]

Glad to hear!

[olive sedge]

Can I get some help with DrawDebugString pls? I can't get it to show up with world location: https://i.imgur.com/zMqSbPn.png this should draw on my character or without the vector node at 0,0,0 but it doesn't show up

Ok, I literally did nothing different and it works now. Odd.. But I'll take it!

[olive sedge]

Yes, I just read this too but it's not true in my case

[dry pewter]

Also, the draw debug node seems to be troublesome depending if you are playing in editor view or standalone game, odd

[olive sedge]

I just tested a bunch of stuff that didn't work, then ^Z'd back to an earlier state and it worked all of a sudden

[dry pewter]

Odd

[olive sedge]

yes

[dry pewter]

Well, off to sleep now

Nights, peeps

[olive sedge]

@trim matrix https://i.imgur.com/maj0Mu7.png

figured it out! Thanks!

[errant viper]

hey can anybody help me with a problem

i wanted to make an animation for my zombie ai

animation blueprint

but the idle is the only thing that works

[azure sparrow]

wat do i do here

whats an object

:/

pls help ty in advance!

[olive sedge]

@azure sparrow well, you gotta have something you want to cast to bp weapons

do you know what you're doing when you're trying to cast?

[azure sparrow]

all i am trying to do is calling a function from another blueprint

and i learnt that casting is the only way to do that

i dont know how to use object

[olive sedge]

you learned wrong ;P

all you need is the object that is instantiated from the other blueprint

[azure sparrow]

and moreover, am i doing it the wrong way?
if so, then pls correct me : D

[azure sparrow]

ah i see but i didnt instantiate any object from any other blueprint

[olive sedge]

you're trying to call fire on your pawn, yes?

[azure sparrow]

yes

[olive sedge]

well, you have a default pawn, the engine instantiates it for you

[azure sparrow]

but the bp_weapons is a parent

[azure sparrow]

:0

how do i get it?

[olive sedge]

GetPlayerPawn for example

[azure sparrow]

lemme try it

thanks!

[olive sedge]

or even better GetControlledPawn

if you're calling it from the controller, which you're probably doing here

THEN you need to cast it

cause the pawn you're getting back is typed as Pawn

[azure sparrow]

no i bp_weapons is an actor

i just enabled input on it

[olive sedge]

tell, then make it a pawn ;P

[azure sparrow]

how to?

[olive sedge]

If you're controlling it with a player controller and it takes input, make it a pawn

[azure sparrow]

i dont know the way to change actors to pawns, could u pls tell me

i am actually new to this engine

[olive sedge]

reparent it in class settings

https://i.imgur.com/E5dVgdz.png

[azure sparrow]

oOO

and also is this happening caz the bp is not a pawn?

[fiery lark]

Does anyone know how to use a megascan on a landscape?

Or as a landscape layer?

[olive sedge]

@azure sparrow yes.. if you're trying to cast a pawn to bp weapons and bp weapons is not a pawn

[azure sparrow]

i see

[azure sparrow]

will i find the class options on the details tab of class defaults?

[olive sedge]

yes

see my screenshot

[azure sparrow]

:/

[olive sedge]

UE5?

[azure sparrow]

yeah that made me get to ue

: D

[olive sedge]

well then good luck ;P

[azure sparrow]

ok i can find the class opttions somehow

lemme try

[olive sedge]

I woulda switched too but my GPU can't handle it and there isn't a new one to be had for reasonable prices

[fiery lark]

It actually runs pretty good, it's the demo they released that is an absolute beast

[azure sparrow]

the demo requires 64 gigs of ram and rtx 2080 and 12 core cpu

f

[azure sparrow]

welp i was looking on class defaults instead of class settings, its right there

if i change the bp to pawn the children classes will also change right?

but now theres another problem

theres no error here

but the function isnt getting called

it isnt printing this

[olive sedge]

@azure sparrow you should learn about breakpoints.. select a node and hit F9

set a breakpoint on the LeftMouseFire call, see if it even calls

@fiery lark well, I don't think around 10fps in an empty editor is "pretty good"

[fiery lark]

U playing on a potato my guy?

[olive sedge]

Ryzen 9 3900X with 48 gig of RAM

it's just my GPU that's bottlenecking me, a GTX 970

[fiery lark]

Oof

I got a 1070 and it get 60 fps

[olive sedge]

yes, well.. an upgrade for just one generation didn't make sense at the time, the 20x generation was horrible value/price and the 30x is just NOT available at all

[azure sparrow]

i see! ty for assisting me : D

[olive sedge]

@azure sparrow for sure

[azure sparrow]

yes i was able to set a break point

now how do i understand if it calls?

[burnt citrus]

hey, are there any differences between two nodes?

[dawn gazelle]

When you press play, if the game stops and directs your attention to where the node is, it triggered.

[sonic pine]

Hiho, I have a little understanding problem. I use the Localization Dashboard and String Tables to translate the game.
Now I have the following problem, every NPC gets this window, but every NPC has one or more different quests. How do I assign the German or English version to the quest window depending on the NPC ????

[olive sedge]

@azure sparrow what Datura said. Your inputs are probably not set up correctly

[dawn gazelle]

The top one is a direct reference to a Blackboard component on an object.
The bottom one is a function that first casts the actor reference to a pawn, then tries to find the Blackboard component, first on the pawn's controller, and if it doesn't find it there, then on the pawn itself. So you could in theory get the blackboard using the function version using a generic Actor reference.

[burnt citrus]

got it, thank you!

[sonic pine]

Any ideas? ^^

[azure sparrow]

oh it didnt :/

isnt this the way?

oh wait no this is not an actor anymore

[azure sparrow]

no it is caz this is working perfectly, but not the next node

[olive sedge]

@azure sparrow well, then your cast is failing. bp weapons is probably not your pawn, is it? what is bp weapons anyway?

[azure sparrow]

it is

u told me to make it a pawn

and i did

[olive sedge]

@azure sparrow in your game settings, what do you have under maps/modes in default pawn?

[dawn gazelle]

I'm handling my dialogue through data tables that use text fields which could then generate the string tables when I'm ready to do localization. So then, when I'm creating a widget that would need to be localized, I'm feeding in the data table entry and populating the fields needed from the data table. That being said, you could probably do the same - instead, you'd define which string table you want to in the text fields within the data table.

[azure sparrow]

by game settings u mean project settings?

[olive sedge]

oh, yes.

[azure sparrow]

i didnt get u

heres the maps

i know i am dumb and pro'lly ur saying right but its me whose not understanding it

[olive sedge]

https://i.imgur.com/m9OCR44.png

[azure sparrow]

should i change the default pawn class?

[olive sedge]

ah. so there.

[azure sparrow]

ok

[olive sedge]

yes

[azure sparrow]

ty

[olive sedge]

change it to bp weapons (probably first person shooter?)

[azure sparrow]

i cant edit these

[olive sedge]

you gotta have your own game mode

[azure sparrow]

oh

ok

[olive sedge]

default game mode would be a boring game, no?

[azure sparrow]

yeah

[sonic pine]

Well, there are unique IDs, my idea so far was to give each NPC the ID of the quest that belongs to this NPC, but I'm not sure how I can access it.

Example:
NPC variables:

1. Min ThirdPersonCharacter LV (5)
   AND
2. QuestID (Quest05)
   BRANCH
   If both are true, the NPC has quest number 5

I think, however, that I then need a widget for each quest that is linked to the NPC and that would be a lot of widgets ^^

Unfortunately I only find Quest systems on Youtube that work without translation, so I don't really have any ideas for implementing this. I've never done anything like this and therefore don't understand how your suggestion should work ^^

[azure sparrow]

yes i set one

but still doesnt work

[olive sedge]

what happens when you start the game, anyway

[azure sparrow]

just normal

the thirdperson character runs

besides i set an ai that follows it

and deals damage when is near

[olive sedge]

ah, I see..

So then that third person character would be your pawn

[azure sparrow]

what i want to do is do everything under bp_weapons and call those from the thirdperson

[olive sedge]

it's probably overridden in the world settings of the level

do you want to keep moving about with the third person character?

[azure sparrow]

yeah

[olive sedge]

and are you calling fire on the TPC?

[azure sparrow]

no later on i will change it obsly

[azure sparrow]

yeah

[olive sedge]

I see.

so then BP_Weapons should not be a pawn

it should be a component on your pawn

[azure sparrow]

:0

yeah if u say so

then, what do i do?

[olive sedge]

are you using the first person or third person?

[azure sparrow]

third

[olive sedge]

yes, I just saw.. well, I'd add a weapon as a component or child actor onto the character and attach it to a socket on the skeletal mesh

[pale orbit]

does anyone know why can't i set variables like this?

[azure sparrow]

but there will be a lot of weapons D;

[olive sedge]

I think there's some logic you could look into in the FPS template but I haven't used that yet

yes, you can switch them out

[azure sparrow]

and the bp_weapons doesnt have a mesh its a parent

[olive sedge]

ok, and the children implement fire?

[azure sparrow]

yeah

[olive sedge]

I see.. well, go with the logic in BP Weapons for now, you can extend it later

[azure sparrow]

but for now i am just trying to make a print string on the functio

[azure sparrow]

i am

for now i am, i am printing a string (trying to)

[olive sedge]

yes.. what you want to do is have a child actor or component on your character that is attached to a socket on the skeletal mesh and then you can easily use that from the character BP

[gentle urchin]

Quality of screenshot is very low, but it seems ur reference type is wrong.

[azure sparrow]

i have attached a mesh, idk how to attach a blueprint to another = (

[pale orbit]

when i print the name of the object ref it shows me "Enemy_Character" as it should but when i try to assign a Enemy_Character variable it tells me its not compatible

[olive sedge]

@azure sparrow either create a component instead of an actor which would probably be cleaner or attach it as a child actor component

[azure sparrow]

i did

[olive sedge]

looking good! 😄

[gentle urchin]

You need to store it as the correct type to be able to access the variable. Go via a cast if the output variable is of the wrong type

[azure sparrow]

but its not a child bp rather a mesh

[olive sedge]

well, it's a static mesh component

[azure sparrow]

yeah

so theres no gain ig

[olive sedge]

yes.. make it a BPC_Weapons component or a child actor component with class BP_Weapons

[pale orbit]

ty @olive sedge

it worked

[azure sparrow]

i have a child bp of the bp_weapons but idk how to add that as a component

[olive sedge]

@azure sparrow on your character do Add like you did with the static mesh

but select Child Actor

btw, that fire should probably be on your character anyway since you'll need an animation and everything

would make more sense to play an animation on the character like "slash" or "fire gun" depending on th type of weapon attached

[azure sparrow]

yeah

[dawn gazelle]

No you don't need to create a widget for each quest. You can feed in the data that the widget needs and then construct what the widget should display from that data. If you create expose on spawn variables on the widget, then you can feed data in when you're going to create it. Then you can use say the below node to grab the appropriate table, and you could feed in the key on creation, then from there populate the fields as needed.

[olive sedge]

just make a component class tree with weapon -> blunt/sword/axe/gun/whatever

[azure sparrow]

did

[olive sedge]

you can still call things on the weapon later

@azure sparrow yes. looking good. on the details for that child actor you can set the class

[olive sedge]

yes

[azure sparrow]

i did but it doesnt show up

[olive sedge]

did you specify the parent socket? doesn't look like it from the bit I see on the shot

[azure sparrow]

no

here?

[olive sedge]

yes

[azure sparrow]

how do i put a socket?

[olive sedge]

there should already be sockets available

use the magnifier

[azure sparrow]

ok

[olive sedge]

@azure sparrow be sure to attach that axe to the mesh

[azure sparrow]

mesh? u mean to the mesh of the child bp?

yes did

[azure sparrow]

used the magnifier but nothing happens

caz its set to none

the socket

[olive sedge]

https://i.imgur.com/t3pBl4N.jpg

[azure sparrow]

i bed ur pardon but i cant see the texts clearly, maybe zoom in and give another one?

[olive sedge]

right click and go open link

[azure sparrow]

ok

how didu set theparent socket?

the socket is not a drop down

[olive sedge]

with the magnifier. but be sure to attach the child actor component to the mesh component of you character

[azure sparrow]

and also in my case will bp_weapons be the parent socket?

[azure sparrow]

yes now it worked i can use the magnifier but what would the parent socket be?

[olive sedge]

depends where you want to attach the weapon. just use hand_r for now

can also attach it to the head if you want to be silly ;P

[sonic pine]

Ok but how i can change the quests? How i can connect Quest 4 to NPC 7 and Quest 5 to NPC 9?

[azure sparrow]

xD

💯

[olive sedge]

perfect.

[azure sparrow]

now could u pls tell me how to make the function work

[olive sedge]

maybe -Z by ~75?

[azure sparrow]

and btw ty for helping me out with a lot of patince

[olive sedge]

for sure

well.. grab the child actor component and drag it into your blueprint grid

[azure sparrow]

ohk

[Help]
Can someone point me to a tutorial for a seamless first-person door open animation to a new level?
Example:
https://www.youtube.com/watch?v=r6NCC-nnvMU&t=70s&ab_channel=GameZone

[azure sparrow]

could u please tell me the name of the node in the middle?

[olive sedge]

get child actor

[azure sparrow]

did

but i connected it directly

[dawn gazelle]

For that you'd need a mission manager component or actor where you can store what missions the player has done and can determine what missions that NPC has available.

[olive sedge]

that won't track

[azure sparrow]

hmm it wont

[olive sedge]

you're trying to cast the child actor component to weapons instead of the actor it's holding

[azure sparrow]

oh so i need to cast to the child actor?

or do i change the child actor to the bp_weapons

[olive sedge]

no, you need to get the actor from the child actor component and then cast that to weapons (see my screenshot)

[gentle urchin]

Also, you dont really wanna cast on every single time you do the "fire" event

[sonic pine]

ah ok i have a Quest_Componend, ok thanks i will try it with 2 differnet npc´s and quests 😉

[azure sparrow]

i didnt get u, also i didnt understand the node in the middle(of ur ss) : (

[pale orbit]

would it be dumb to store a player variable inside gameinstance?

[olive sedge]

drag the child actor component into the grid, drag out from the blue pin and find get child actor component, connect that to cast

[pale orbit]

cant seem to be able to cast to playerstate

[azure sparrow]

done
